DS1923-F5

The DS1923 temperature/humidity logger iButton™ is a rugged, self-sufficient system that measures temperature and/or humidity and records the result in a protected memory section. The recording is done at a user-defined rate. A total of 8192 8-bit readings or 4096 16-bit readings, taken at quidistant intervals ranging from 1s to 273hr, can be stored. Additionally, 512 bytes of SRAM store application-specific information and 64 bytes store calibration data. A mission to collect data can be programmed to begin immediately, after a user-defined delay, or after a temperature alarm. Access to the memory and control functions can be password protected. The DS1923 is configured and communicates with a host-computing device through the serial 1-Wire® protocol, which requires only a single data lead and a ground return. Every DS1923 is factory lasered with a guaranteed unique 64-bit registration number that allows for absolute traceability. The durable stainless-steel package is highly resistant to environmental hazards such as dirt, moisture, and shock. Accessories permit the DS1923 to be mounted on almost any object, including containers, pallets, and bags. A Shield/Umbrella is required to protect the top of the device from direct water droplets and rain.

EXTREME CAUTION: A PROTECTION SHIELD/UMBRELLA MUST BE USED TO PROTECT THE TOP OF THE CASE FROM EXPOSURE TO LIQUIDS AND THE DEVICE MUST NOT BE SUBMERSED IN LIQUID. TO DO SO WILL CAUSE THE DEVICE TO MALFUNCTION AND INVALIDATE THE DEVICE WARRANTY
